US copper futures climbed to a one-week high in early business on Monday, driven by a weaker dollar and an increase in Chinese imports, but another large build in London warehouse stocks capped some of the bullish momentum.
Copper for March delivery rose 1.10 cents to $1.3375 a lb by 10:22 am EST (1522 GMT) on the New York Mercantile Exchange's COMEX division. The range from $1.3195 to $1.4595, its loftiest level since December 15. Comex estimated volume at 3,633 lots by 9 am.
